Abstract: 1,161,970. Choline-chloride compositions. KONINKLIJKE INDUSTRIEELE MAATSCHAPPIJ NOURY & VAN DER LANDE N.V. 14 March, 1968 [17 March, 1967], No. 12535/68. Heading C2C. A process for preparing a dry, free-flowing, non-hydroscopic composition containing choline-chloride comprises preparing, in an aqueous choline-chloride solution, a finely-divided alkali metal salt of a fatty acid and subsequently drying the resultant mixture. Preferably the composition contains 0À25 kg. of fatty acid alkali metal salt per kg. of choline-chloride, and may be prepared by adding the desired fatty acid to a vigorously stirred aqueous choline-chloride solution and subsequently adding sodium or potassium hydroxide such that the pH is adjusted to about 8.

Abstract: 911,848. Variable-speed gear. ANDREWS, W. R. March 27, 1961 [April 8, 1960], No. 12642/60. Class 80 (2). In a variable ratio friction gear of the kind described in Specification 809,136, wherein a disc 8 on one shaft 3 projects between a pair of discs 9 on another shaft 5 and is inclined thereto to form V-shaped gaps into which a pair of friction rollers 12 or balls are urged to make friction driving contact between the discs, the surfaces 13, 14 of the discs are conical so that during ratio shift the rollers 12 move towards or away from the shaft axes in a plane inclined to a plane perpendicular to either shaft axis. As shown, the shaft 3 is the input shaft, 5 an intermediate shaft, and a further pair of rollers 12, adjustable with the first pair, transmit drive to a disc 11 fast on an output shaft 7 parallel with the input shaft. The rollers 12 are carried by plates 18 mounted for limited transverse movement on a carrier 20 which during ratio shift guides the rollers 12 along a path in which they have no tendency to precess, and are pressed into the V-gaps by springs 29. For ratio-shift the plates 78 are, as shown, traversed along cam guide rails 28 by a screw 34. Alternately the cam guides may be moved longitudinally, the plate 18 following the movement. Ratio shift may also be effected by bodily move m ent of the shaft 5. The number of discs, intermediate shafts and rollers used may be increased to increase torque capacity.

Title: Improvements in or relating to latching mechanisms
IPC: E05B65/19
Filed: 1951-05-30
Abstract: 686,088. Latches. HOUDAILLE-HERSHEY CORPORATION. May 30, 1951 [Aug. 8, 1950], No. 12707/51. Class 44. A latch e.g. for the door of a luggage compartment in a motor-vehicle body comprises a supporting plate 17, Fig. 1 mounted parallel to the path of swing of the door 22, a projecting portion 16, Fig. 3, of the plate being adapted to pass through an opening 15 in a keeper 12 secured to the door frame. Slidably and pivotally mounted on the plate 17 is a latch lever 19 the pivot pin 53 of which is movable in a slot 54. A spring 55 surrounding the pin 53 urges the lever 19 in an anticlockwise direction and towards the lower end of the slot 54. A dogging lever 27 pivoted to the plate 17 at 44 has an arm, the end 37 of which is normally supported by a lip 35 projecting from a key operable spring loaded lever 29 arranged on an extension plate 28 parallel to the outer panel of the door. A pin 49 carried on another arm 47 of the lever 27 engages in a slot 51 of the latch lever 19. As the door closes the end 60 of the lever 19 engages the keeper at the side of the opening 15 as shown in Fig. 3. This causes the pivot pin 53 to slide upwardly in the slot 54 and the lever 19 to rotate in a clockwise direction about the pin 49 of the dogging lever 27. This rotation displaces the end 60 of the lever 19 so that it passes through the opening 15 whereupon the lever 19 is moved to the position of Fig. 4 by the spring 55, the inside cam surface 59 engaging the edge of the opening 15 to retain the door shut. To open the door, the lever 29 is turned by the key 34 and the dogging lever 27 released to move in an anticlockwise direction so that the latch lever may turn in a clockwise direction to allow the door to open. As soon as the latch lever is clear of the keeper it turns in an anti-clockwise direction under the action of the spring 55, this movement turning the dogging lever 27 back in a clockwise direction so that its cam-shaped end 38 snaps behind the key-operable lever 29. The latch mechanism is then ready for the re-latching operation.

Abstract: Organic compounds liable to deterioration from peroxide formation selected from aldehydes, esters of unsaturated carboxylic acids and ethers are stabilized with from 0.001 to 1 per cent by weight of a tetra-alkylated dihydroxy stilbene of the formula <FORM:0699180/IV (b)/1> wherein R1 and R2 represent alkyl groups, preferably containing not more than eight carbon atoms.  The dihydroxy stilbene may be 3,31 - dimethyl - 5,51 - ditertiary butyl - 4,41 - dihydroxy stilbene or 3,31,5,51-tetra-tertiary butyl-4,41-dihydroxy stilbene. In the example nonaldehyde is stabilized with each of the two specific dihydroxy stilbenes referred to above. Tetrahydrofuran is referred to as a suitable ether in the Provisional Specification. Specification 699,079 is referred to.  Tetra-alkylated dihydroxy stilbenes of the above general formula are prepared by reducing alkyl stilbene quinones of the general formula <FORM:0699180/IV (b)/2> where R1 and R2 have the above significance.  The reduction may be carried out with ferrous or stannous chloride with an agent which will liberate nascent hydrogen, e.g. zinc and acetic acid, or by means of catalytic hydrogenation, e.g. in the presence of platinum, palladium, nickel or ruthenium.  The compounds 3,31-dimethyl - 4,41 - dihydroxy - 5,51-ditertiary butyl stilbene and 3,31,5,51-tetra-tertiary butyl-4,41 dihydroxy stilbene are prepared from the corresponding stilbene quinones using zinc and glacial acetic acid as the reducing agent.ALSO:Petrols liable to deterioration from peroxide formation are stabilized with from 0.001 to 1 per cent by weight of a tetraalkylated 4, 41-dihydroxy stilbene of the general formula: <FORM:0699180/III/1> wherein R1 and R2 represent alkyl groups, preferably containing not more than eight carbon atoms.
